Answers to Your Engineering Questions
We understand that building projects come with many questions, which is why we’ve compiled answers to the most common concerns.
Old or inefficient windows can increase energy bills by up to 30%, create uncomfortable drafts, and lead to condensation issues. Replacing them improves comfort, energy efficiency, property value, and even security.
Low-E (Low-Emissivity) glass reflects heat back into your home in winter and blocks solar heat in summer, improving comfort and reducing energy costs.
Signs include drafts, condensation between panes, difficulty opening/closing, visible damage, or windows over 15 years old.
Yes. Modern triple-glazed windows with argon gas can cut heating costs by up to 30% annually in Ontario’s climate.
